Need help with slope:

"Write each equation in standard form"
y + 9 = -3(x - 2)

can you help me understand this? There are 8 questions total so I would like a detailed answer please! Thank you!!

The Standard Form for a linear equation in two variables, x and y, is usually given as
Ax + By = C

anonymous · Answer

where A B and C can be represented by numbers

anonymous · Answer

What would A B and C be represented by in this equation?

anonymous · Answer

They're constants that you'll get from whatever algebra you have to do to get the x and y in the right place.

anonymous · Answer

In this case you should start by distributing the $-3$ and then combining all of your constants.

anonymous · Answer

the first step, in this case, would be to distribute the -3

anonymous · Answer

Distributing it to the other side?

anonymous · Answer

Distributing the $-3$ in $-3(x-2)$ means multiplying the terms in the parentheses by -3 to get $-3x + 6$.
